Either update gnulib (or at least threadlib.m4) or add

export gl_cv_have_weak=no

to the cygport (or set it as an environment variable during configure).

The newer binutils changed they way weak symbols (which are not
available for non-ELF platforms) are treated for PE/PEP object files and
that triggered a latent bug in how gnulib tested for their usability.
The binutils issue is still under investigation, I expect that the next
release will have a fix.

Achim.
